Pins defined in target not being assigned

[User-256]

Hi,

I am trying to port this flight controller: BetaFPV F405 V3 AIO into Inav.

I have used the following as references:

• src/utils/bf2inav.py to get a starting point
• Betaflight Config: BEFH-BETAFPVF405.config as input to "bf2inav.py"

So far the motors spin and gyro+accel seem to be ok.

However, the battery voltage and current sensor are not working (both were working in Betaflight).

Whilst trying to debug this issue I noticed that some of the pins defined in the "target.c" and "target.h" files I created show as "FREE" in the output from the CLI command "resource". For example:

Output from CLI command "resource":

ADC definition in "target.h":

If my understanding of how this should work is correct, I think I would expect the pins defined in the target files to be populated in the output of the "resource" CLI command?

I was wondering if anyone with more experience could comment on whether my understanding is correct? is there anything obvious that I have missed or configured incorrectly? any other suggestions of things I could try to debug this would be greatly appreciated!

Thanks for your help 😄

Please attach the complete files you are working with, and the output of "status".
A settings dump could also be useful.

Be sure you have those features turned ON in the Configuration tab of Configurator.

Target files (work in progress): BETAFPVF405.zip

Output of "status" below. Looking at the "status" output, it seems that the ADCs are configured but none are used.

Thanks 👍 this explains the UART4 pins (enabling UART4 assigned the pins), is there a settings to "use" the configured ADCs?

Be sure you have those features turned ON in the Configuration tab of Configurator.
